I agree virtualised server performance is lower than equivalent hardware, but order of 4 magnitude seems very high and improbable.

Some of the difference comes about due to the number of cores in the machines we purchased - they are 16 core machines (each E5-2650 has 8 cores.)
In terms of storage, we are utilizing HDFS with commodity 3TB drives, thus no specialized storage from EMC (or the like.)
This is high margin business, look Amazon P/E ;-)
